Summary:
As PFAS regulations continue to evolve, effective and permanent treatment solutions are increasingly critical for landfill operators, industrial dischargers, and municipalities. Revive Environmental has developed and deployed a treatment system that integrates foam fractionation (FF) with supercritical water oxidation (SCWO) to remove, concentrate, and destroy PFAS compounds from complex liquid waste streams. Foam fractionation is a physical separation process that leverages the surface-active properties of PFAS to concentrate them into a foamate without the use of chemical additives. In a recent field deployment at a large U.S. landfill, a FF system was used to treat PFAS-contaminated leachate. The system successfully separated targeted compounds, including PFOS and PFOA, into a concentrated foamate stream. The concentrated foamate was transported to Revive’s PFAS destruction facility, where it was treated using supercritical water oxidation (SCWO). Operating above the critical point of water, SCWO enables complete oxidation of organic contaminants. Third-party laboratory analysis confirmed PFAS reduction to levels below current EPA drinking water standards. The treated effluent was safely discharged under Revive’s existing environmental permits. By combining efficient separation with proven destruction, the FF + SCWO solution provided the landfill operator with a comprehensive treatment approach that reduces long-term liability, meets current and anticipated discharge regulations, and minimizes operational disruption. The project demonstrates a practical, scalable model for PFAS lifecycle management, offering industry partners a clear and measurable path toward compliance and risk reduction.
